Synopsis

Keywords: Blood vessels, Phantoms, blood vessels, aneurysms, diagnostics, treatment evaluationTreating life-threatening intracranial aneurysms with flow modulating devices (FMDs) is mostly successfull, but may lead to complications and even delayed aneurysm rupture. A biomarker indicating treatment success is direly needed. Flow MRI can detect flow reduction, but it is impaired by metal artifacts from FMDs. Black-blood (BB) MRI is less sensitive to metal artifacts and often results in poor slow-flow suppression. We hypothesize that BB contrast changes after aneurysm treatment. Here, after placing FMDs in 3D-printed aneurysm models, an enhanced signal was found on BB MRI, associated with the reduced aneurysmal flow after flow modulation and thus possible treatment success.
